Make an ESX Firewall Rule Manageable in the vSphere Client

Make an ESX Firewall Rule Manageable in the vSphere Client. To do so, you essentially need to create a new service in the firewall configuration XML file.

Open the file /etc/vmware/firewall/services.xml
Scroll to the bottom & note the last Service ID #
Copy an existing service section as a template (ie. faultTolerance)
Paste as new following proper XML formatting
Increment the Service ID # by 1 ensuring it’s unique
Customize to fit your new inbound/outbound port rule
Save and exit
Services do not need to be restarted
